Java Spring搭配Junit测试配置

使用Junit测试时，如果项目用Spring框架的话，配置文件载入什么的很麻烦，而且和数据库的连接经常出错，可以使用spring的注解配置，简化代码，让测试结果更有效。

环境

IDE：idea
JDK：1.8
Junit：4.9
Spring：4.26

maven配置

spring测试相关的

<properties>    <file.encoding>UTF-8</file.encoding>    <spring.version>4.2.6.RELEASE</spring.version></properties><dependency>    <groupId>org.springframework</groupId>    <artifactId>spring-test</artifactId>    <version>${spring.version}</version></dependency><dependency>    <groupId>org.springframework</groupId>    <artifactId>spring-jdbc</artifactId>    <version>${spring.version}</version></dependency><dependency>    <groupId>org.springframework</groupId>    <artifactId>spring-aop</artifactId>    <version>${spring.version}</version></dependency><dependency>    <groupId>org.springframework</groupId>    <artifactId>spring-aspects</artifactId>    <version>${spring.version}</version></dependency>

Junit

<dependency>    <groupId>junit</groupId>    <artifactId>junit</artifactId>    <version>4.9</version></dependency>
